Mechanical engineering
Individual. Reliable. Secure.

3defacto develops economical special machines of the highest quality. Many years of experience and specialisation in engineering services from a single source enable mechanical engineering “Made in Germany”, where individual wishes and requirements are optimally implemented. This is already evident in the planning, the selection of the individual hardware components, the project-related production engineering on our own premises, the adapted control technology and finally the turnkey, energy-efficient machine. This has allowed us to deliver optimised, individual machines to many satisfied customers, which remain impressive for their economic efficiency, reliability, and high safety standards even after many years.

In order to permanently fulfil our own demand for qualitative competence and the latest know-how, 3defacto consciously promotes the exchange of experience and knowledge between engineers from design and mechanical engineering. The result can be seen in many successful engineering projects and innovative designs in special-purpose engineering.
